Bravo to “The Economist” magazine for putting innovation and toilets on their cover in January 2013. It is a very timely and inspiring cover given the Reinvent the Toilet Challenge initiative.

The S-trap flush toilet was created in 1775 by Alexander Cummings. This trap uses standing water to seal the outlet of the bowl, preventing the escape of foul air from the sewer. His design had a sliding valve in the bowl outlet above the trap. This technology has changed little in the last 230 years.

The term “water closet” or WC was coined in the UK around 1870. The term “water-closet” was an early term for an interior or exterior room with a flushing toilet in contrast to an earthen closet often found outdoors.

RTI is bringing an “I” for innovation to the WC concept, piloting an approach to use a “WiC” to ignite solid waste as part of our off-grid liquid and solid waste treatment system.
